87 | Karl Friston on Brains, Predictions, and Free Energy

If you tell me that one of the world's leading neuroscientists has developed a theory of how the brain works that also has implications for the origin and nature of life more broadly, and uses concepts of entropy and information in a central way — well, you know I'm going to be all over that. So it's my great pleasure to present this conversation with Karl Friston, who has done exactly that. One of the most highly-cited neuroscientists now living, Friston has proposed that we understand the brain in terms of a free energy principle, according to which our brains are attempting to model the world in such a way as to minimize the amount of surprise we experience. It's a bit more complicate than that, but I think we made great headway in explicating some very profound ideas in a way that should be generally understandable.

Someday, most likely, we will encounter life that is not as we know it. We might find it elsewhere in the universe, we might find it right here on Earth, or we might make it ourselves in a lab. Will w...

We gather empirical evidence about the nature of the world through our senses, and use that evidence to construct an image of the world in our minds. But not all senses are created equal; in practice,...
